xenserver error fsck

Dashrender

Hold on dude..
your data is still probably just fine..

As long as XC still works, pull the data i mentioned before - find all the uuid's from all drives and their mounted order to each VM and write it down.
then you'll shut down the server, replace the USB drive, then install XS then install updates,
then attach SR
then start remaking your VMs by hand and attach your VDIs to the VMs and boot

@DustinB3403 Or a clone / image of the USB?

Nothing recent enough to try I don't think. I do have a clone of this USB though.

Make another copy and then boot from that. What's the worst that could happen?

BRRABill

Yeah I would definitely try...

booting from your cloned USB
reinstalling XS and recreating your VMs by hand as Dash has suggested
doing a restore

In that order.

I played with XS a lot moving the boot drive and stuff and it was pretty resilient.

DustinB3403

How do I get the disk UUIDs for the Vm's?

momurda

@DustinB3403
xe vm-list
or
xe vdi-list for disks

I wonder if that will work for him?

Seems like anything the host has to do fails...

momurda

If those wont work in cli, you still can use XC to get this info. Or XO i imagine has this info listed on its web interface.

DustinB3403

we're probably going to migrate everything over (but guess when.... next flipping weekend...)

DustinB3403

Is there a way to use xe vdi-list against specific VM's so I can see it all?

Danp

@DustinB3403 WTF... that makes mo sense. Why wait?!

In XC, click the VDI, and then STORAGE (on the menu) and COPY UUID TO CLIPBOARD.

https://discussions.citrix.com/topic/292483-how-can-i-list-vhd-uuid-and-its-associated-vm-name-and-sr/?p=1576369

Gives a list of all SRs and their contained VDIs.

DustinB3403

im just not seeing it

BRRABill

Does it work from XC? If not, I don't think you are going to be able to get it.

DustinB3403

from within XC I'm not seeing UUID's on the drives them selves.

DustinB3403

is this the kind of thing I'm looking for?

uuid ( RO) : 6e599b8b-6894-4f56-b4e7-2aa8a79e463c
name-label ( RW): Tom Training
name-description ( RW):
sr-uuid ( RO): ab4b21fd-1157-d4ca-cd4d-78cb4affee2a
virtual-size ( RO): 107374182400
sharable ( RO): false
read-only ( RO): false

@Dashrender what steps did you go through to restore, can you send me what you had to follow directly?

Chances are it won't live that long if you're having these issues already.

Danp

@Dashrender That's what I was thinking as well.
